PerfectDisk 2000 - www.raxco.com -
Schedulable, defragments pagefile directories and MFT and is the only commercial
defragger capable of defragmenting ALL of the NTFS metadata ($LogFile, $Bitmap,
etc...). PD2k runs on Win9x, WinMe, WinNT 4.0 and is certified for Win2k.
From a central point you can schedule defrag activity throughout. No difference
in functionality between the workstation and server version (both the workstation
version AND server version can schedule through the network). PD2k is a "one
pass" defragger - designed to do the job in one pass. PD2k also works very
well with minimal usable freespace - as low as 5% where others may require
alot more. PerfectDisk also does a excellent job of consolidating freespace
- which means that the partition re-fragments slower. PerfectDisk uses the
MS provided API's for defragging files. The user interface can be confusing.

Diskeeper - www.execsoft.comRecommended: Schedulable, defragments pagefile directories and MFT
but is unable to defragment the rest of the NTFS metadata. DK runs on Win9x,
WinNT 4.0 and is certified for Win2k. Requires their Server version if you
want to schedule defrag activity through the network. May require multiple
passes to completely defrag a partition. Diskeeper strongly suggests that
you have at least 20% freespace in order to effectively defrag. Diskeeper
uses the MS provided API's for defragging files.

O&O Defrag - www.oo-defrag.com.
Recommended: Schedulable, defragments pagefile and MFT but doesn't
defragment the rest of the NTFS metadata. You have to purchase their "Network
Addition" which allows you to schedule through the network. O&O Defrag
is a "one pass" defragger - designed to do the job in one pass. They have
a separate Network Edition of their defragger that I believe does network
scheduling but it slots into their own MMC type "framework". Works well in
lower freespace conditions. O&O Defrag uses the MS provided API's for
defragging files.

Speedisk 5.x - www.symantec.com. Schedulable, defragments pagefile, directories
and MFT but is unable to defragment the rest of the NTFS metadata. SD runs
on WinNT 4.0 and Win2k. Requires purchase of their Norton System Center if
you want to schedule defrag activity through the network. SD is a "one pass"
defragger - designed to do the job in one pass. Works very well in low freespace
conditions. SpeedDisk also does a excellent job of consolidating freespace
- which means that the partition re-fragments slower. SpeedDisk is the only
defragger that does NOT use the MS provided API's for defragging files.

OnTrack's Suite - www.ontrack.com. A suite of products. You can't just buy
the defragger. Schedulable. Works on NT 4 and Win2k. Don't know too much
more about this one. Ontrack's defragger uses the MS provided API's for
defragging files.

Defrag Commander and Defrag Commander NE - www.winternals.com. Remotely defrags
NT and Win2K systems, also schedules the built-in defraggers on WinMe/9x
and optionally Win2K. Works as an MMC snap-in. The NT/Win2K defrag engine
is designed to do the job in "one pass" using the Microsoft defrag APIs but
with no software installed on the systems being defragged. Defrag Commander
also provides it's own defrag engine which does a far better job than using
the Win2k built-in defragger. Provides no offline/ boot time defragging of
pagefiles, directories or NTFS metadata.

Vopt - www.goldenbow.com. Works on NT4 and Win9x. Not sure if it works under
Windows 2000. I don't know much about this defragger.

Did you know that NT (XP, etc...) systems (servers or workstations)
will "fight" for the right to be the master browser (keep the list
of who is on the network) unless you tell them not to? This is the cause
of the "The master browser has recieved a server announcement from the
computer..." error from Rdr with Event ID 8003. Contrary to some missinformation
on web, the correct setting in
\\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters
for the MaintainServerList is FALSE. it is NOT No, NO, False, etc... it has
to be set to "FALSE" (without the quotes)
